Hello everybody.

I New to the forum here, I have a program I need to use for video editing (Glmixer) compiled with opencv 2.4 running on Debian Squeeze. I get good video resolution with my Logitech web-cam, but the display resolution with the capture cards is a whopping 48X32 pixels..!

How do I get into opencv to set the resolution higher? I know very little about opencv other than all that code just causes me mass confusion. I read some info on the BT878 cards needing the CVS version, yet I do get output, just lousy resolution. The resolution is fine on everything in Guvcview and Cheese.

Thank's a lot!

Hi,

OpenCV use FFmpeg to deal with reading / writing images and to access to video stream. You can try to use: http://docs.opencv.org/modules/highgu... to force the size of the acquired image

video_capture.set(CV_CAP_PROP_FRAME_WIDTH, 640);
video_capture.set(CV_CAP_PROP_FRAME_HEIGHT, 480);
